Explanation
Unstructured data refers to data that does not conform to a specific, pre-defined data model. It tends to be the human-generated and people-oriented content that does not fit neatly into database tables.
In the given options, D. PNG and F. MP4 are examples of unstructured data.
PNG (Portable Network Graphics) is a file format used for lossless image compression. PNG images can contain color palettes, grayscale images, and full-color non-palette-based RGB/RGBA images, making them a popular choice for storing graphics on the web.
MP4 (MPEG-4 Part 14) is a digital multimedia container format most commonly used to store video and audio, but it can also be used to store other data such as subtitles and still images.
On the other hand, XML, CSV, XLS, and JSON are all structured data formats. They all have a level of organization and hierarchy, and they can all be easily parsed and understood by software programs.
